truth of this is that Treasure never gave Red a defined gender. Sure, they have feminine attributes, but that could be put down to the armour giving them hips (like it does for Blue as well), and sure you could point to the eyelashes but eehh. Red uses more "masculine" leaning language in japanese, and nobody refers to Red as a girl in the game apparently, but in the west they were like "uhh... Red's a girl i guess."
...Gunstar Super Heroes was kinda a trip tbqh with its story mind.
@avi also yeah the first I heard about it was seeing the cartridge in like... Either fuckin Game or some kind of smaller independent gaming store here in Sheffield and just being like "WHAT... A SEQUEL?!?!"
I played the living hell outta it and got every ending hhhhh.
